Abstract
An ultrasound Doppler measurement system for measuring the flow velocity field of magnetically driven liquid metal is presented: Two orthogonally arranged ultrasound Doppler sensor line arrays each with 25 piezo elements allow the two dimensional measurement of two flow velocity components (2d/2c) in an area of 70 x 70 mm!. To obtain a high spatial and a high temporal resolution, a specific multiplex moe for controlling the line array elements is used. First measurement results of liquid metal flows driven by a rotating magnetic (RMF) field are shown.
